Replacements of roof, rain gutters, windows, and furnace on a residential rental property are capital improvements to the structure because they materially add to the value of your property or substantially prolong its life. The items would be in the same class of property as the rental property to which they are attached. Since the property is residential rental property, the items are generally depreciated over a recovery period of 27.5 years using the straight line method of depreciation and a mid-month convention.

Repairs, such as repainting the residential rental property, are currently deductible expenses. A repair keeps your property in good operating condition. It does not materially add to the value of your property or substantially prolong its life. Repainting your property inside or out, fixing gutters or floors, fixing leaks, plastering, and replacing broken windows are examples of repairs. If you make repairs as part of an extensive remodeling or restoration of your property, the whole job is an improvement. In that case, you should capitalize and depreciate the repair costs as the same class of property that you have restored or remodeled as discussed above. For more information, refer to Publication 527, Residential Rental Property, and Publication 946, How to Depreciate Property.
